Abstract

A chip package includes a thermal interface material disposed between a die backside and a heat sink. The thermal interface material includes a first metal particle that is covered by a dielectric film. The dielectric film is selected from an inorganic compound of the first metal or an inorganic compound coating of a second metal. The dielectric film diminishes overall heat transfer from the first metal particle in the thermal interface material by a small fraction of total possible heat transfer without the dielectric film. A method of operating the chip includes biasing the chip with the dielectric film in place.
